It was designed to be used exclusively by programmers and became a leading operating system for workstations because of its portability, flexibility, and power. Unix is a multi-user and multitasking operating system developed in the 1960s in AT&T Labs. Software developers Ken Thompson and Denis Ritchie, who’s considered the father of C language, are credited for their valuable input in the development of the system which soon found its way in academia.

From here, you can abstract the dates in many languages. strtotime() is just so you can convert a normalized date into an actual unix timestamp for cross language/platform compatibility. not much else to it.

Unix was developed in AT&T’s Bell Labs back in the mid-to-late 1960’s. The initial release of Unix had some important design attributes that live on today. One is the “Unix philosophy” of creating small, modular utilities that do one thing and do them well.

Unix is primarily a command line based operating system with additional applications, such as X Window System, to give a graphic oriented operating system similar to Windows. Since Unix is often used from the command line, there are various shells. A shell is a large add-on or modification of the Unix operating system. UNIX is a general-purpose, interactive time-sharing operating system for the DEC PDP-11 and Interdata 8/32 computers.

Using Unix Time With Command Line Tools. On Linux and macOS, the date program is the core utility for dealing with date/time, including Unix timestamps. Called without any arguments, it returns the current date/time in a human-readable format:

Data storage and These workloads exploit the latest features of the z/OS runtime environments, including Parallel Sysplex, Workload Manager (WLM), and UNIX System Services Inner workings of Synology Hybrid RAID.

Unix has been ported to more machine families than any other operating system. Unix -- often spelled UNIX, especially as an official trademark -- is a multi-user operating system designed for flexibility and adaptability. Originally developed in the 1970s, Unix was one of the first operating systems to be written in C language.
